Computer repeatedly types "=" regardless of keyboard attached

Computer repeatedly types "=" regardless of keyboard attached

I have an HP L2310CU notebook. I've run every diagnostic I could. The entire PC DR suite, memtest86, et cetera. Everything came back just peachy. I physically removed the notebook keyboard. I've used USB keyboards (three different models). I've uninstalled windows, then installed XP, followed by Vista, followed by Ubuntu. No matter what I do, whenever possible the computer just prints a continuous flow of equal signs, as if a key is stuck. Even when no keyboard is present at all.

"I would try using the Windows On-Screen keyboard utility or the Ubuntu Live CD to see if this is a hardware or software issue. On Windows XP, you can find this tool under All Programs - Accessories - Accessibility - On-Screen Keyboard.

Try typing with the on-screen keyboard, not your keyboard. If all characters are coming out correctly, then I would think you have a hardware issue with the machine.

If the characters still come out with the '=' character, I would try formatting and reinstalling Windows again, perhaps it wasn't done correctly before (maybe an Upgrade was chosen instead of a clean install?)"

"I don't know if your laptop would boot, but can you disconnect your built-in keyboard and try it with an external keyboard.

Also if possible, check the difference between a ps2 and usb keyboard.

My guess would be either the built-in keyboard has a problem or it is the motherboard.."
